1. Malware: Malware is a broad term used to describe any malicious software that infiltrates a computer system, such as viruses, worms, Trojan horses, and spyware. Malware can slow down a computer by using up valuable system resources, disrupting essential system services, or corrupting files and data.
2. Cluttered Hard Drive: A cluttered hard drive can slow down a PC due to the fact that it has to search through a large number of files before it can find the one it needs. This can be remedied by either deleting old files or moving them to an external storage device.
3. Insufficient RAM: Random access memory (RAM) is a type of memory used by computers to store data that is currently being processed or used. If there is not enough RAM, then the computer will have difficulty running certain tasks quickly, resulting in a slow-down.
4. Outdated Software: Outdated software can slow down a PC because it hasn’t been designed to run on the most recent hardware and thus requires more resources in order to function. This can be remedied by updating the software to the latest version.
5. Overheating: When a computer overheats, its performance can suffer. This can be caused by dust buildup inside the computer, inadequate cooling systems, or issues with the power supply.
